You can run Travis-CI locally, in a docker image, in order to test your travis-ci.yml configuration file.

See "How to Run TravisCI locally on Docker": you can open a travis bash with:

docker run -it -u travis quay.io/travisci/travis-jvm /bin/bash

That article is about giving that local Travis instance access to your GitHub repo, but in your case, you can make a docker image (based on one of the Travis-CI ones) which would mount the local repo folder you have on your machine, and will be able to do a travis compile in that mounted folder within the container.

If the test passes in your local Travis-CI, then you can push your local commits to your GitHub repo.
